Abstract: The study presents a comparative analysis between first and all-
author co-citation analyses, as well as comparison between two matrix 
generation approaches. We thus continue the latest research in author co-
citation analysis (ACA), where the results of the traditional first-author 
analyses based on ISI citation indexes are challenged by incorporating all-
authors from the cited references. Identifying all cited authors from 
references in source papers is an extremely cumbersome process if the 
Thomson ISI citation indexes are used as a basis. Due to the difficulty in 
obtaining all-author co-citation data few such studies exist. In order to 
study all-authors co-citation we use a citation index generated from 
documents in XML code. This allows us to carry out a comparative study 
between first and all-author co-citation analyses based on the hitherto 
largest set of references and the broadest domain of research.
